Use Delta Web to find a teammate’s thread, send a message, or review changes without installing Delta. You need a Zed account and must accept Delta’s Early Access Agreement. See Sign In for more.
Browse threads
Open delta.dev/threads and sign in with your Zed account. Select a thread to open it in your browser.
To find your own threads or a teammate’s, open the filter menu in the header on a wider screen. On a phone, tap the floating filter button at the bottom right to open the filter sheet:
- Find threads you own: under Threads, choose My Threads.
- Find a teammate’s thread: choose All Threads. You can find threads you have joined and threads shared with everyone in the selected organization.
- Find a thread in another organization: under Organization, choose that organization. The list starts with your default organization and shows one organization at a time.
Use Previous and Next at the bottom to browse more threads. Bookmark the page to return to the same organization, filter, and page.
Find a missing thread
If a thread does not appear, check the organization and choose All Threads. If it is still missing:
- Ask for the link. A thread shared with Anyone with the link only appears in the list once you are a member.
- Ask the owner to invite you. A private thread only appears if you have access.
- Open a local-only thread in the desktop app and share it. Threads must be synced to Delta’s servers to appear on the web.
See Collaborate in a Thread for sharing and invitation instructions.
Install Delta Web
To open Delta Web from your Home Screen, visit delta.dev/threads and install it from your browser’s menu:
- Safari on iPhone: choose Share > Add to Home Screen, turn on Open as Web App, then tap Add.
- Chrome on Android: choose Install and create shortcut from the browser menu, then tap Install.
- Firefox on Android: choose More > Add app to Home screen from the browser menu.
Installing it adds a Home Screen icon, not the desktop app. You still need an internet connection and a Zed account. To create top-level threads or work with local projects, install the desktop app.
Inbox and notifications
Open Inbox to see thread invitations and mentions. The Inbox and its unread indicator update automatically. On a computer, Inbox appears at the top of the left sidebar when the sidebar is open. In a thread on a phone, tap the Inbox button in the header. Opening a thread marks its mentions and invitation as read, even if you did not open it through Inbox. A notification for a mention in a file or diff comment opens that comment.
For system alerts, turn on Desktop notifications in Settings > General and allow notifications when your browser asks. Alerts cover mentions and invitations while Delta Web is open. The choice applies to this site in this browser profile. If notifications are blocked, allow them in your browser’s site settings; some browsers do not support them.
Settings in the browser
Your account settings sync between desktop and web. Browser settings use LLM Providers for model connections and your Zed subscription details. Desktop-only controls, such as App Icon, are not available in the browser.
Join without installing Delta
Open the shared link and sign in with your Zed account.
The link opens the thread in your browser, whether you’re on a computer, phone, or tablet. On a computer, you can choose Open in Desktop App in the thread header if you’d rather use the native app.
The link takes you to the sender’s position in the thread.
Work in a thread
Send messages, add comments, and review changes alongside teammates using the desktop app. You can read the thread’s files and diffs without cloning the project.
Work on a computer
To find an action, open the command palette with Cmd+Shift+P on macOS or
Ctrl+Shift+P on Linux and Windows.
To continue in the desktop app, choose Open in Desktop App in a shared thread’s header. If you are viewing a subthread, Delta opens that subthread. The control’s menu also offers Download Delta if you haven’t installed it. This control is not shown on touch devices.
To start a review, open the eye menu in the parent thread’s header and choose Start Review, or select an existing review. In the review, choose Submit Review to approve or request changes. See review threads for how review edits and verdicts reach the parent.
You can also send a message to a fork from an existing thread, including another fork. This works on desktop and web.
Run View All Subthreads or press Cmd+J on macOS or Ctrl+J on
Linux and Windows to find the parent’s children. Filter by kind, and press
Tab to show or hide archived children. Open a child in a tab, then use
Open as Primary to give it the main conversation area.
Select the added/removed line counter in the bottom bar to review the thread’s changes.
To create and share a new top-level thread or manage its projects, use the desktop app, then open the thread in Delta Web.
Work on a phone
The tab bar below the thread title keeps Thread, Changes, Files, and any open files or documents together. Tap Changes to review the diff or Files to browse the thread’s projects. Open a file to give it its own tab; scroll the tab bar sideways to find open tabs, and tap a tab’s close button to close it. In a subthread, the conversation tab is labeled Subagent, Review, or Merge where applicable.
Tap the menu button at the top left of a parent thread to open the conversation’s thread list in a bottom sheet. Choose a subthread to open it, or choose All Threads to return to the thread browser. In a subthread, use the back arrow to return to its parent.
Tap More in the header for Reviews, Merge, and Search, where available. When viewing a diff or file, this sheet also has display controls such as Line Numbers and Comments or Comment Mode. The controls vary with the tab you’re viewing. Use the controls below the conversation to choose a model or runner; the send button floats above them. Tap Message Overview to jump between turns.
To start a review, choose Reviews > Start Review from More in the parent thread. In a review, choose Submit Review to approve or request changes. See review threads for how review edits and verdicts reach the parent.
Place the cursor on a comment or linked response to see navigation actions
such as View Reply, Go to Original Comment, or Go to Comment Target.
When the keyboard is open in the composer, use the formatting controls for
bold, italic, or inline code. The selection toolbar lets you copy text,
copy a link’s address, or copy a link to your location in the thread.
Choose where to run a request
Choose an execution environment based on what your request needs:
- Work with the thread’s synced files: send a browser turn using a Delta-hosted model. The agent can read the thread’s diffs. Browser turns do not have a disk checkout or shell, so they cannot run terminal commands.
- Use your computer’s tools, credentials, or running processes: open the thread in the desktop app and run the turn on your computer, or enable it as a Personal Runner and select it in the browser’s runner menu while it’s online.
- Run commands without your computer: choose Cloud in the composer’s runner menu to use a Cloud Runner. The turn runs in a cloud sandbox with a shell and a checkout of the thread’s Delta worktrees.
Claude Agent turns run only in the desktop app. The browser shows them, and offers Switch to Delta to continue with Delta’s agent.
To bring changes into your local repository, use the desktop workflow.
See Collaborate in a Thread for how execution environments differ between participants.
